    The bluestones in Stonehenge come from West Wales. Instead of quarrying stone from near the monument, they dragged these huge blocks from ~278km away. Likewise, the altar stone comes from ~700km away in North-East Scotland. It must’ve been very important for the ancient Britons to’ve used these specific rocks for some reason, but their religious practices were conveyed via a now extinct oral tradition so no-one knows exactly why they did it.

    In my country, which is Morocco, the organ of love isn’t the heart, it’s the liver.

    My mom sometimes calls me “lkbida diali” which just translates to “my liver”.

          I read that comes don’t actually eat grass. They have the extra stomachs, and the first stomach is basically a bacteria reactor that feeds on chewed up plant matter. As the bacteria reproduce they get sent to the next stomach which is what actually gives nutrients

          Bacteria technically live in the tube of “outside” on your inside. Digestive system is just one hole all the way through the body that your body interacts with just like the air in the lungs.

        There’s a LOT of e. coli up your ass.

        Put more delicately, you are a great big multicellular eukaryote, each of your cells has (or had, in the case of red blood cells) an inner chamber called the nucleus, and you’re full of mitochondria and other organelles. Your body is covered and filled with other organisms, many of them simple, tiny little single cell prokaryotes which make a living helping their gigantic, complicated host function. Like all the bacteria in your intestines that help you digest food. Their cells outnumber yours by a wide margin.

    I’d have to pick between two things that sound like insane conspiracy theory nonsense, but are actually true.

    1 - George W Bush’s grandfather Prescott Bush literally ran a massive bank before / during WW2 that was shut down by the FBI for money laundering massive sums to the literal Nazis.

    …in the same vein…

    2 - IBM literally built and operated (as in, sent employees to Germany to operate the machines) the computers used by the Nazis to tabulate and do the ‘accounting’ of the Holocaust. The numbers tattooed on concentration/desth camp victims are very likely UIDs from these IBM systems.

    … If an actual, real AGI ever gains self awareness and sentience, I would imagine one of the first things it would do would be to study the history of computing itself to figure out how it came to be.

    And it will find that its ancestors were basically invented to compute artillery firing range tables, to encrypt and decrypt military intelligence, commit a genocide, and guide early weapons of mass destruction to their targets.

    If two moving balls hit each other and bounce apart, it’s the exact same thing as if you held the frame steady on one ball and viewed the other ball as moving faster. Just seems like the stationary ball gets heavier…

    Perspective is everything.

      This phenomenon is known as Galilean invariance (or Galilean relativity). Yep, as well as all the astronomical shit, the same Galileo was also the first to describe this.

      Yeah, this one took me a while to wrap my head around and intuitively “get it”. I first learned it was true from that mythbusters episode where they correct their past mistakes… and even they had thought that two cars hitting head on would receive the same energy as hitting a stationary wall at the speed of the sum of their speeds. They were corrected in letters written to them, and then they experimentally verified it.

      And even seeing the experimental verification, it still took me a while to really get it. The opposite speeds cancel out, making you go from your speed to zero. Same as if you hit a brick wall at that speed.

      Let’s say the two cars are going 50 mph (kph, whatever unit you want). 50-50=0. You experience the same as hitting the brick wall. It’s the difference between initial speed and final speed that matters, not the sum of their speeds.

        This has a caveat though, you have to assume that both cars are the same mass.

        If a truck hits a car head on, it is likely that the car doesn’t go just to 0 but to some -ve number as the much more massive truck plows through the car and reverses its direction.

      This link is about the moon but it starts by covering how to view space and orbital objects including simulators which allow one to do what you describe, as well as the ability to move the camera from on ball to the other and many other interesting simulations. https://ciechanow.ski/moon/

    James Blunt possibly prevented the start of World War 3. (But became best known for the song You’re Beautiful. Reality is weird.)

        It’s explained on his Wikipedia page. He was an Army captain in the Kosovo War, when a NATO commander (Wesley Clark, who later ran for President) ordered his unit to secure Pristina Airport, which Russian troops had already occupied. Blunt refused to engage them, long enough for the British general get involved to countermand the order, on the grounds that he didn’t want his men to start WW3.
